Beauty instruments are important tools in modern beauty and skincare. They provide users with various beauty functions through technological innovation. However, for a good beauty instrument, in addition to its functional advantages, the design aspect is also crucial. ### 01. Design Principles of Beauty Instruments 1. **Functionality**: The primary consideration in the design of beauty instruments is functionality. The design of beauty instruments should meet users' functional requirements for various beauty needs. For example, skincare instruments need to have multiple functions such as cleaning, hydrating, and firming, while beauty devices should be equipped with functions like electric treatment, massage, and hydration. Designers should carefully consider users' needs to ensure that the design of beauty instruments can satisfy these demands. 2. **Ease of Operation**: The design of beauty instruments should take into account users' experience. Ease of operation is an important design factor. Users should be able to easily understand and use the beauty instruments. Designers should make the use of beauty instruments simpler and more convenient through clear and intuitive operation interfaces, easy-to-master usage methods, and human-computer interaction design. 3. **Safety**: As electronic products, safety is one of the essential factors to consider for beauty instruments. Designers should follow safety design principles to ensure that beauty instruments do not cause harm to users during use. For instance, designing products with waterproof performance to prevent water from seeping into electronic components, and developing a reasonable power management system to avoid potential safety hazards such as overheating and electric shock. 4. **Ergonomics**: The design of beauty instruments should conform to ergonomic principles, making users feel comfortable and natural during use. Designers should consider factors such as the size, weight, grip feel, and shape of the beauty instruments, so that users' hands and faces can get comfortable support and fit, reducing fatigue during use. 5. **Aesthetics and Brand Image**: Finally, the design of beauty instruments should focus on aesthetics and brand image. Through elegant appearance, exquisite materials, and meticulous detailing, beauty instruments can present a high-quality and professional feel. Designers should fully consider the target users and brand positioning of the product, integrating the brand's style and image into the design of beauty instruments to enhance the product's attractiveness and competitiveness. ### 02. How to Design Instrument Products? 1. **Clarify Design Content**: After confirming the design cooperation with customers, our marketing and design personnel will communicate with customers to understand the design content and the goals to be achieved by the instrument product design. 2. **Design Research**: Design research is an essential step in the design process for industrial designers. During this process, industrial designers must understand the sales status of the instrument, its stage in the life cycle, the situation of competitors' instrument products, and the opinions of users and sellers on the instrument products. These are the basis for design positioning and creative design. For household beauty instrument products, the design difficulty mainly lies in the attractiveness of the appearance and the accuracy of shape positioning, as well as how to shorten the design cycle to seize the ever-changing mass consumer market. 3. Discuss Rough Structural Arrangement of Instrument Products with Customers: After positioning the concept of the instrument product, we will confirm the rough structural arrangement of the instrument product with customers, analyze the feasibility of technology, cost budget, and commercial operation, and understand customers' basic ideas about the instrument product. 4. Conceive Instrument Product Sketches: The work in the sketch conception stage will determine 70% of the cost of the instrument product design and the effect of the instrument product design, so this stage is the most important in the entire instrument product design process. Ideas are formed through thinking and quickly recorded. The ideas in this initial design stage often appear as instant inspirations, lacking accurate size and geometric information. Based on the designers' ideas, various forms are sketched or design information is recorded with annotations, and three to four directions are determined for further in-depth design by designers. 5. Complete Instrument Product 2D Renderings: 2D renderings refine and precise the vague design results in the sketches. This process can be completed through CAD software. Through this link, accurate 2D design drawings of the instrument product's appearance are generated, which can clearly show the size and approximate volume of the instrument product to customers, express the material and light-shadow relationship of the instrument product, and are a more intuitive and complete expression after the design sketches. 6. Instrument Product 3D Design Drawings: 3D modeling is the process of describing the shape and structure of the instrument product in 3D language. Its greatest advantage is the intuitiveness and authenticity of the design. By observing and adjusting the shape of the instrument product from multiple angles in a 3D space, part of the original prototype trial-manufacturing process can be omitted. It can more accurately and intuitively conceive the structure of the instrument product, thereby expressing the product concept more specifically and improving the quality of the instrument product design. 3D drawings have accurate shape proportional relationships and exquisite detail designs, which can be directly used for communication with customers. 7. Multi-Angle Renderings: Multi-angle renderings provide a more intuitive way to feel the spatial volume of the instrument product from multiple visual angles. 8. Instrument Product Color Design: Instrument product color design is used to meet customers' requirements for color series of instrument products. Preliminary color schemes are formulated through computer adjustment to meet different color needs of the same instrument product and expand customers' instrument product lines. 9. Instrument Product Surface Logo Design: The design and arrangement of surface logos on instrument products will become the highlight of the panel, bringing users a brand-new life experience. 10. Instrument Product Structural Sketch Design: Design the internal structure, installation structure, and assembly relationship of the instrument product, and evaluate the rationality of the instrument product structure. 11. Instrument Product Wireframe Structure Drawings: Accurately complete the electronic files of each part of the instrument product and the assembly relationship between parts according to the design dimensions. 12. Instrument Product Structure Explosion Diagrams: Analyze whether the assembly relationship between parts is reasonable, whether there is interference, and analyze the load strength of each component. 13. Modify Wireframe Structure Drawings: Modify and adjust the problems in the structural design to determine the final structural files. 14. Prototype Production: Complete the structural prototype production through CNC (Computer Numerical Control) or RP (Rapid Prototyping). 15. Prototype Debugging: Install all circuits and parts into the prototype model, inspect the rationality of the structural design, experience the use feeling of the instrument product design, and make final adjustments to the problems found to reduce the risk of mold development. ### 03. Trends of AI Smart Home Beauty Instruments 1. **Demand and Development**: With the rapid rise of the beauty industry, people's demand for personal beauty and skincare is constantly increasing. AI smart home beauty instruments have emerged to meet this demand. They can not only help users achieve younger and healthier skin but also provide personalized skincare advice to meet the needs of different users. 2. **Core Technologies**: The core of AI smart home beauty instruments lies in artificial intelligence and big data analysis.
